Abstract

The deformation due to creep has an important effect on the behavior of concrete structures especially for their long term integrity. Undesirable consequences may appear in the structures due to incorrect or inaccurate prediction of creep deformation. A large database coming from international laboratories and research centers is used in order to compare the experimental results with the Eurocode 2 creep prediction. This study shows that the Eurocode 2 underestimates the important creep compliance and overestimates the small creep compliance. In order to overcome this inaccuracy, new correction coefficients are introduced to the formulas of the Eurocode 2 using an Approximate Bayesian Computation method based on the rejection algorithm.
